Safety Precautions
I_WARNING .
Improper installation, adjustment, altev_tlon, service or maintenance can cause DEATH, SERIOUS BODILY
INJURY, OR PROPERTY DAMAGE. Refer to this menu- at for assistance or consult your local Sears Service
Center for further information.
AWARNING
WATER HEATERS EQUIPPED FOR ONE TYPE GAS
ONLY: This water heater is equipped for one type gas only. Check the model rating plate near the gas control valve for the correct gas, DO NOT USE THIS WATER
HEATER WITH ANY GAS OTHER THAN THE ONE SHOWN ON THE MODEL RATING PLATE. Failure to
use the correct gas can causeproblems which can result in
DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. If you have any questions or doubts consult your gassupplieror local utility.
AW_!_tRNING
INSTALLATIONS IN AREAS WHERE FLAMMABLE LIQ- UIDS (VAPORS) ARE LIKELY TO BE PRESENT OR
STORED (GARAGES, STORAGE, AND UTILITY AREAS, ETC), Flammable liquids (such as gasoline, solvents,
propane (LP) or butane, eta), all of which emit flammable vapors, may be improperly stored or used in such areas.
The gaswater heater pilot light or main burner can ignite such vapors. The resulting flashback and fire can cause death or serious bums to anyone in the area, as well as
property damage.
If installation in such areas is your only option, then the installation must be accomplishedin a way that the pilot flame and main burner flame are elevated from the floor at least 18 inches.While this may reduce the chances of flammable vapors from a floor spill being Ignited, gasoline
and other flammable substancesshouldnever be sto_l or used in the same room or area contain ng a gas water
heater or other open flame or spark producing appliance. NOTE: Flammable vapors may be drawn by air currents from other areasof the structure to the appliance.
AWARNING
If this water heater will be used in beauty shops, barber
shops, cleaning, establishments, or self-service laundries with dry cleaning equipment, it is imperative that the water heater or water heaters be installed so that com-
bustlon and ventilation air be taken from outside these areas. Refer to the "Facts to Consider About the Location" section of this manual and also the latest edi- tion of the National Fuel Gas Code, ANSI Z223.1, also referred to as NFPA 54 for specificsprovided €oncemnin air required.

A WARNING
At the time of manufacture this water heater was previd-/ ed with a combination temperature-pressures relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or materials, as meeting the requirements for Relief Valves and Automatic Gas Shutoff Devices for
Hot Water Supply Systems, and the latest edition of ANSI Z21.22 and the code requirements of ASME. If replaced, the valve must meet the requirements of local codes, but not lessthan a combination temperature and pressure relief valve certified as meeting the require- ments for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22 by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or materials.
The valve must be marked with a maximum set pressure not to exceed the marked hydrostatic working pressure of the water heater (150 Ibs./sq. in.) and a discharge capacity not less than the water heater input rate as shown on the model rating plate. (Electric heaters. watts divided by 1000 x 3415 equal BTU/Hr. rate.)
Your local jurisdictional authority, while mandating the use of a temperature-pressure relief valve complying
with ANSI Z21.22 and ASME, may require a valve model different from the one fumnishedwith the water heater.
Compliance with such local requirements must be satis- fied by the installer or end user of the water heater with a locally prescribed temperature-pressure relief valve installed in the designated opening in the water heater in )lace of the factory furnished valve.
For safe operation of the water heater, the relief valve must not be removed from it'sdesignated opening or
plugged.
The temperature-pressure relief valve must be installed directly into the fitting of the water heater designated for the relief valve. Positionthe valve downward and pro- vide tubing so that any dischargewill ex'_ only within 6 inches above, or at any distance below the structural floor. Be certain that no contact is made with any live electrical part. The dischargeopening must not be blocked or reduced in size under any circumstances. Excessivelength, over 30 feet, or use of more than four
elbows can cause restrlctionand reduce the discharge
capacity of the valve.•
No valve or other obstruction is to be placed between the relief valve and the tank. Do not connect tubing
directly to discharge drain unlessa 6" air gap is provided. To prevent bodily inlury, hazard to life, or property dam- age, the relief valve must be allowed to dischargewater in quantities should circumstances demand. If the dis- charge pipe is not connected to a drain or other suitable means, the water flow may cause property damage.
The Discharge Pipe:
•Must not be smaller in size than the outlet pipe size of the valve, or have any reducing couplings or other restrictions.
Must not be plugged or blocked.
Must be of material listed for hot water distribution.
Must be installed so as to allow complete drainage of both the temperature-pressure rehef valve, and the
dischargepipe.
Must terminate at an adequate drain.
Must not have any valve between the relief valve and tank.
